prob_rebuilt_goal: Calculate the probability of reaching a rebuilding goal

In ktmurray1219/mmrefpoints: Project Marine Mammal Populations and Calculate Reference Points

Description

function that calculates the probability of recovery (in terms of 1+ numbers) to MNPL (or other population size) at rebuilt.yr years

Usage

prob_rebuilt_goal(traj, goal = 2000, rebuild.yr = 100)

Arguments

traj	a matrix of trajectories, with rows=nsims and cols=nyears
goal	rebuilding goal as an absolute number of animals
rebuild.yr	the year by which you want pop to be recovered (calculate probability that pop will recover to MNPL by rebuild.yr)

Value

- the probability that the stock will be rebuilt to the goal population size by year rebuilt.yr
